To request that a job be run using striping, you must modify the network statement in your job command file. Shown here are examples of IP and user space network modes.
To submit a job using IP striping, your network statement would look like this:
network.MPI = csss,,IP
To submit a job using user space striping, your network statement would look like this:
network.MPI = csss,,US
For more information on the network statement, see network.
